William Wentworth-Fitzwilliam, Viscount Milton

William Wentworth-Fitzwilliam, Viscount Milton MP (27 July 1839 – 17 January 1877) was a British nobleman, explorer, and Liberal Party politician.

Early life
Fitzwilliam was the eldest son of William Wentworth-FitzWilliam, 6th Earl FitzWilliam, and his wife Lady Frances Harriet Douglas, daughter of George Douglas, 17th Earl of Morton.

An epileptic, William was educated at Eton and Trinity College, Cambridge.

Career
Arriving in Quebec City in July 1862, Milton and Dr Walter Butler Cheadle traveled across the North American continent, wintering near Fort Carlton. After a challenging and at times humorous summer they reached Victoria, BC. Together with Butler Cheadle, he traveled up the Athabasca River and in 1863 they became the first "tourists" to travel through the Yellowhead Pass.

They later co-authored "The North-West Passage by Land" and " Voyage de l'Atlantique au Pacifique, à travers le Canada", which described their expedition in considerable detail.

Following his adventure in Canada, Milton entered politics and became one of the youngest members of the House of Commons. He represented the West Riding of Yorkshire South between 1865 and 1872.
